Definitions

  • the present invention relates to an antenna device for a mobile radio communication apparatus, a so-called cell or mobile telephone, and designed for operation in at least two frequency bands, comprising at least a first antenna element connected to the circuits of the mobile telephone.
  • One method of increasing antenna performance would be to employ telescopic rod antennas, but at least in the lower frequency bands that are employed in mobile telephony, even such a rod antenna designed as a quarter wave antenna would hardly have room interiorly inside the apparatus casing, since, for example, in the GSM band, an antenna length of approx. 80 mm would be required. Complex mechanical solutions would be called for to achieve the integration of such an antenna.
  • the present invention has for its object to design the antenna device intimated by way of introduction such that its performance may be drastically improved without the physical dimensions of the apparatus casing of the mobile telephone of necessity needing to be increased.
  • the present invention further has for its object to realise an antenna device which obviates the drawbacks inherent in prior art technology.
  • the present invention has for its object to realise an antenna device which is simple and economical in manufacture and which facilitates impedance adaptation to the circuits of the mobile telephone.
  • the antenna device intimated by way of introduction is characterised in that the first antenna element has at least a first and a second radiator of a surface extent which is shaped so as to comply with the configuration of an adjacent part of the inside of a casing in which the mobile telephone is accommodated.

  • Fig. 5 is a view corresponding to that of Fig. 3, in yet a further modified embodiment
  • Fig. 6 is a view corresponding to that of Fig. 3, but in still a further modified embodiment
  • Fig. 7 is a perspective view of a second embodiment of an antenna device according to the present invention.
  • Fig. 8 is a second perspective view of the antenna device according to Fig. 7;
  • Fig. 9 shows a first alternative of the interconnection of two radiators included in the antenna device according to Figs. 7 and 8;
  • Fig. 10 shows a second alternative of the interconnection of two radiators included in the antenna device according to Figs. 7 and 8;
  • Fig. 11 shows a third alternative of the interconnection of two radiators included in the antenna device according to Figs. 7 and 8.
  • reference numeral 1 relates to an upper part of an apparatus casing for a cell or mobile telephone.
  • This casing may be both an inner casing which, in such instance, is included in the mechanically bearing parts of the mobile telephone, and an outer casing which substantially fulfils aesthetic functions.
  • a circuit card 2 Interiorly in this casing, there is disposed a circuit card 2 with the circuits of the apparatus.
  • a first antenna element 3, which is in the form of an inner or permanent antenna 3, has two radiators 4 and 5, where, for example, the longer radiator, which is designed as a meander, may be dimensioned for GSM bands (880-960 MHz), while the shorter radiator 5 which, in the illustrated embodiment, is a rod antenna, may be dimensioned for the DCS- or PCS bands or both (1710-1880 MHz and 1850-1990 MHz, respectively).
  • Both radiators 4 and 5 are interconnected to each other by the intermediary of a connecting member 21 which realises a galvanic parallel connection of the radiators whereby the impedance is reduced to such a low level that a specific matching network may many times be dispensed with.
  • the radiators have a common supply section 6 which is galvanically connected to the two radiators and further galvanically connected to the circuits on the circuit card 2. Between the two radiators 4 and 5, there is a dielectric such as air, glass, a suitable plastic material etc.
  • the inner antenna 3 is dimensioned in order alone to be able to function satisfactorily, at least in environments where the reception conditions are good or normal.
  • the first antenna element 3 is disposed in or on and positionally fixed by means of a retainer device which, in this embodiment, is an integral part of the casing 1 of the apparatus.
  • the retainer device is formed by the inside 14 of the upper end wall of the casing 1 and a wall 13 projecting from the inside of the casing.
  • the antenna element is interlockingly fixed in tight connection to the inside 14 of the casing.
  • connection 21 realises a separation of the radiators 4 and 5 so that, also in the longitudinal direction of the connecting member, they will be positioned closely adjacent inner surfaces, e.g. a rear surface 22 on the back portion of the casing 1.
  • the two radiators 4 and 5 are arcuate in shape, whereby their shape is adapted to closely conform with the configuration of adjacent inner surfaces of the casing.
  • An outer antenna 7 is disposed on or together with or integral in a wrist strap, a neck strap or some similar accessory to the mobile telephone itself.
  • the outer antenna 7 may therefore be seen as an accessory which greatly improves antenna performance, and which may be important in areas where reception conditions are less satisfactory. If, for purposes of exemplification of the outer antenna 7, we use a neck strap, this has a first part 8 and a second part 9 which are brought together in an, eye 10 which is fixable in an anchorage 11 on the apparatus casing 1 physically close to the inner antenna 3. While not being apparent from Fig.
  • the outer antenna has a lightly flexible, metallic conductor whose dimensioning is such that, when, as a result of its physical proximity to the inner antenna 3, it is capacitatively/inductively connected to it and can operate with half wave operation in the frequency range to which the radiator 4 is set, up to full wave operation in the frequency range to which the radiator 5 is set.
  • the metallic conductor in the outer antenna 7 may be a thin, lightly flexible metal wire. It is further apparent from Figs. 1 and 2 that the apparatus casing 1 has, just beneath the anchorage 11, a through-going, elongate aperture 12 which, interiorly in the apparatus casing 1, is defined by the surrounding wall 13.
  • FIG. 2 clearly shows how the antenna 3 is placed in this space and how it is shaped according to and follows the inner surfaces 14 and 22 of the casing 1.
  • the through-going and elongate aperture 12 is also intended for the passage of an alternative to the neck strap with the parts 8 and 9, for example a wrist strap.
  • Figs. 3 and 4 show one embodiment where there is disposed in the outer antenna 7, a single conductor 15 which constitutes a second antenna element if the inner antenna 3 is considered as a first antenna element.
  • the conductor 15 has an end region or a coupling portion 16 which is located physically proximal the first antenna element.
  • the distance between the coupling portion 16 and the first antenna element should be of the order of magnitude of 0.01-0.03 wavelengths.
  • the embodiment according to Fig. 3 has its counterpart in a situation where there is disposed in the outer antenna 7 a metallic conductor only in one of the two parts 8 and 9.
  • Fig. 4 shows a similar embodiment with a single conductor 15 which constitutes the second antenna element.
  • the coupling portion 17 has, however, a different appearance and extends at least partly about the first antenna element 3. In the embodiment according to Figs. 1 and 2, this would imply that the neck strap or the wrist strap is passed through the through-going aperture 12 straight through the apparatus casing 1.
  • Fig. 5 shows an embodiment where a double or duplex conductor 18 is employed as the second antenna element.
  • This has its counterpart in Figs. 1 and 2 by the situation that both the first part 8 and the second part 9 of the neck strap or the wrist strap each have their part of the duplex conductor 18. The region of union between these parts constitutes the coupling portion 19 of the second antenna element.
  • this embodiment has its counterpart in a situation where the outer antenna 7 is secured in the anchorage 11 of the apparatus casing.
  • Fig. 6 shows a similar embodiment where the outer antenna 7 is secured in the through-going aperture 12 of the apparatus casing so that the coupling portion 20 of the second antenna element at least partly extends around the first antenna element.
  • the inner antenna i.e. the first antenna element
  • the inner antenna element 3 may be produced from a double-sided circuit card, a flexifilm secured on a suitably shaped carrier or vehicle of plastic or other suitable material, or a metalisation of the carrier, the retainer device or the inside of the casing.
  • the first antenna element may be a helical antenna which lies with its longitudinal direction approximately parallel with the width direction of the apparatus casing. Other configurations of the first antenna element are also possible.
  • the uppermost part of the apparatus casing 1 is made as a loose component which may be snapped in position on the rest of the apparatus casing.
  • the counterpart to the anchorage 11 is located on this additional unit, this also accommodating the counterpart to the first antenna element.
  • a counterpart to the aperture 12 may be disposed either in the additional unit or in the joint between it and the apparatus casing proper, but possibly also in the apparatus casing itself.

  • the antenna element 3 is positionally fixed interiorly in the casing 1 by means of a retainer member which is designed as an integral part of the casing of the apparatus.
  • the retainer member positionally fixes the antenna element by the intermediary of a mechanical, interlocking engagement.
  • the radiators of the antenna element 3 are applied direct on interior surfaces in the apparatus casing 1. The radiators will hereby have a surface extent which is adapted to follow the configuration of these interior portions of the inside of the casing 1.

L'invention a trait à un dispositif d'antenne comportant au moins un élément antenne (3) possédant deux éléments rayonnants (4 et 5), placé sur un élément de retenue (23). L'élément de retenue peut se présenter sous la forme d'une unité séparée, mais peut également faire partie intégrante du boîtier (1) d'un téléphone mobile ou cellulaire. Afin que l'efficacité de l'antenne soit améliorée et que l'adaptation d'impédance soit facilitée, les éléments rayonnants sont connectés en parallèle (21) et sont conçus de manière à posséder une étendue de surface dont la forme coïncide étroitement avec celle des surfaces intérieures du boîtier. Dans un mode de réalisation, un élément rayonnant extérieur (7) comprend une partie de connexion placée dans une position physiquement proximale par rapport à l'élément antenne (3), ce qui permet d'établir une liaison capacitive/inductive entre l'élément rayonnant extérieur (7) et l'élément antenne (3).
